In all honesty as many whips that I've had the closest I've been to ECU tuning was a HKS EVC & COBB Tuning AccessPort on my R35 GTR.
Unless waaaaaay back in the day I had a 1990 Honda CRX that I did a Jackson Racing ECU swap and eventually when did a twin cam engine swap and turbocharged it I went to a ACCEL Direct Fuel Injection system ...
But I don't think either was a true ECU tune ... lol
